Hi,
I have created a function in which I am trying to use the expect command for sftp but it is not working. While copying the same in another script(test.sh) it is working.
CAN YOU PLEASE LET ME KNOW WHY THE SAME IS NOT WORKING IN FUNCTION?

function is as follows
Code:
         function smsiuc_ftp()
        {
                        spawn sftp ftp_dl@10.132.249.50
                        expect "ftp_dl@10.132.249.50's password:"
                        send "database123#\n"
                        expect "sftp>"
                        send "put ZTE_*201505*\n"
                        expect "sftp>"
                        send "bye\n"
                        EOF
                fi
        }


error is as follows:
Code:
 smsiuc_ftp
-bash: spawn: command not found
couldn't read file "ftp_dl@10.132.249.50's password:": no such file or directory
-bash: send: command not found
couldn't read file "sftp>": no such file or directory
-bash: send: command not found
couldn't read file "sftp>": no such file or directory
-bash: send: command not found
-bash: EOF: command not found
cat: output.log: No such file or directory
Null message body; hope that's ok

test.sh script in which sftp is used which is working fine is as follows
Code:
 #!/usr/bin/expect
spawn sftp ftp_dl@10.132.249.50
expect "ftp_dl@10.132.249.50's password:"
send "database123#\n"
expect "sftp>"
send "put ZTE_*201505*\n"
expect "sftp>"
send "bye\n"
exit
~

That's because neither spawn nor expect, send or EOF are bash commands; they're expect commands. A "shebang" (quite close to which you get in test.sh; remove the leading space) will run the script with the command indicated.
In post#1, the password might be requested because sftp is not run from within expect but as an independent command. Try embedding it in a here document (c.f. man bash)

Thanks RudiC for the comments. But we cannot set the expect in function which is my exact requirement. Can you please throw some light on this for the way out of using it in function?

Note that sftp is specifically designed to prevent you from doing what you are trying to do because it is an extremely bad and insecure method of transferring files. That is why you are forced to use the expect brute-force password injection tool to inject passwords into it brute-force. It would be better to cooperate with the way sftp is designed to work, and use passwordless keys.

You might want to consider Corona688's comment, though. With ssh and keys installed, you could even simpler just scp files over, sort of on the fly.
